Abstract (en)
The present invention resides in a computer-implemented method for wellbore construction management, comprising storing a set of wellbore policies and procedures set by a wellbore operator, the policies defining limits relating to wellbore operating parameters and/or guidance in response to incidents encountered during drilling that fall outside expected operating conditions; generating a set of procedures defining construction of the wellbore according to an initial well plan, the set of procedures including drilling operating parameters to be used at any point along the wellbore to be drilled; calculating a set of well states from the initial well plan and the generated set of procedures, the set of well states comprising predetermined parameters of the wellbore expected to exist at each of a plurality of depths of the wellbore being drilled; receiving from the wellbore at least one drilling operating parameter measured at a particular depth during drilling; determining at least one well state parameter from the measured drilling operating parameter; calculating a difference between the at least one calculated well state parameter and the corresponding predetermined well state parameter for the particular depth of the wellbore, when the difference exceeds a selected threshold, generating a modified well plan and a new set of procedures defining construction of at least part of the wellbore to the modified well plan; determining that the modified well plan and the new set of procedures is compliant with the stored wellbore policies and procedures set by the wellbore operator; and communicating the modified well plan to a plurality of users.
